A shop owner has described the moment a "half-naked man covered in blood" looked "possessed" after a woman was "stabbed to death" at a house in north Hull.

Karl Pinder, joint owner of the Candy Corner Sandwich Bar, watched in horror as a man was seen running in and out of a house in Milldane, Orchard Park, wearing just a rugby vest and "covered in blood" on Tuesday morning.

Humberside Police has confirmed a woman, 21, was killed and a murder investigation had since been launched. A 23-year-old Hull man has been arrested.

Mr Pinder, 35, said: "We could hear some noises coming from the house. At first we were laughing and joking because it sounded like someone was having a really good time.

"Then the next thing we saw was the man run out of the house totally naked apart from a rugby vest he had on.
